标准范围
ISO 15590-3:20 04适用于焊颈法兰和盲法兰（全面、凸面和RTJ槽）以及锚定法兰、旋转环法兰和孔板法兰。ISO 15590-3:20 04规定了ISO 13623定义的石油和天然气工业管道运输系统中使用的碳钢和低合金钢锻造法兰的技术要求。ISO 15590-3:20 04指定了满足行业匹配ISO 3183管道需求的法兰类别。这些法兰用于正常和低温使用，并包括酸性使用所需的补充要求。ISO 15590-3:20 04不包括工厂焊接延伸件、螺栓连接材料、垫圈、滑动法兰或法兰配件的材料或附件。ISO 15590-3:20 04不适用于阀门、泵或其他设备的整体铸造或锻造法兰。ISO 15590-3:20 04不包括法兰类别或压力等级的选择。ISO 7005-1中列出并适用于ISO 15590-3:20 04的尺寸和压力等级如下:DN 10(NPS 1/2)至DN 1500(NPS 60)；PN 20（150类）、PN 50（300类）、PN 100（600类）、PN 150（900类）、PN 250（1500类）、PN 420（2500类）。
ISO 15590-3:2004 applies to weldneck and blind flanges (full face, raised face, and RTJ groove) as well as anchor, swivel-ring flanges and orifice flanges.ISO 15590-3:2004 specifies the technical requirements for carbon steel and low-alloy steel forged flanges for use in pipeline transportation systems for the petroleum and natural gas industries as defined in ISO 13623.ISO 15590-3:2004 designates those categories of flanges that meet the industry's need to match ISO 3183 pipe. These flanges are for normal and low-temperature service and include supplementary requirements where required for sour service.Materials for, or the attachment of, factory-welded extensions, bolting materials, gaskets, slip-on flanges or flanged fittings are not covered by ISO 15590-3:2004.ISO 15590-3:2004 is not applicable to integrally cast or forged flanges for valves, pumps or other equipment.ISO 15590-3:2004 does not cover the selection of the flange category or pressure class. Sizes and pressure classes listed in ISO 7005-1 and applicable to ISO 15590-3:2004 are as follows:
- DN 10 (NPS 1/2) to DN 1500 (NPS 60);
- PN 20 (class 150), PN 50 (class 300), PN 100 (class 600), PN 150 (class 900), PN 250 (class 1500), PN 420 (class 2500).
